Abstract
The sheet metal stamping is an important part of engineering industries, which is now widely used in many fields including automobiles, electric machineries, electric equipments and instruments. The stamping technology and die are an important means to achieve stamping, to ensure the quality of the stampings and to lower the cost of the workpiece. The development of stamping technology and increasingly demand on stamping products poses a severe requirement for stamping design which consists of structure design and process design .
The present paper describes the design process of punching - blanking die of reinforced plate of car spare wheel carrier, which design the die framework by Auto CAD. It can be finished by one forming process. To ensure the precision of the stampings, the designer includes a good many influencing factors such as die machining, die assembly and the production efficiency of the stampings and so on, also carry out detailed calculations.
